Hay,
I have been accepted as crew with BA and was measured at ny interview as being 5' 2" however I also went for an interview with Virgin and they measured me as 5' 1 1/2" so I didn't go any further. I was a bit gutted at the time as Virgin was my first choice but what can you do? I always knew I was borderline height wise and am just glad BA reckon I'm tall enough!!
My advice?? Don't go for a job where you don't make the height limits, its not worth the time and effort cos they won't budge, just go for airlines that you reach the minimums for.
Good Luck!!
